Description

Android has it own formatter for bytes, but with this utility, there's no need to pass a Context.

Demo Code


//package com.java2s;

public class Main {
    /**/*from   w  w w  . j a v a  2  s  .c  om*/
     * Android has it own formatter for bytes, but with this utility, there's no need to pass a Context.
     * In AppListAdapter we do not have to pass a context yet, so let's keep this method.
     */
    public static String humanReadableByteCount(long bytes, boolean si) {
        int unit = si ? 1000 : 1024;
        if (bytes < unit)
            return bytes + " B";
        int exp = (int) (Math.log(bytes) / Math.log(unit));

        String pre = (si ? "kMGTPE" : "KMGTPE").charAt(exp - 1)
                + (si ? "" : "i");

        return String.format("%.1f %sB", bytes / Math.pow(unit, exp), pre);
